Gravity is a force that causes all objects to be attracted to each other.

Gravity affects all objects.

Gravity pulls us down towards the centre of the Earth.


If person A drops the cog it will fall towards the centre of the Earth. If person B drops the spanner it will fall towards the centre of the Earth.

Gravity is what keeps the Earth orbiting the Sun.


The planets are pulled towards the sun by gravity.

Gravity is a force that causes all objects with mass to be attracted to each other.

Gravity is a non-contact force because it can act without objects touching.

All objects are affected by gravity.

Gravity is the force that pulls objects to the ground.

Isaac Newton was the first to realise that gravity is the force that holds the planets in orbit around the Sun.

When an object accelerates towards the ground gravity is causing a mechanical energy transfer.

When an object decelerates away from the ground gravity is causing a mechanical energy transfer.
